- 87 percent of 685 samples taken from the Wallkill watershed fail to meet Environmental Protection guidelines for safe swimming or other recreational activities where ingestion of water or full body contact is likely.
- Average levels of contamination (as measured by the geometric mean, a type of average) are more than 10 times the EPA safe swimming criterion (Wallkill Entero count of 380.7 vs. EPA criterion of 30).
- Contamination levels vary from place to place, but are elevated throughout the river’s course, indicating the need for action to reduce contamination from multiple sources in multiple communities.
- The Wallkill is particularly affected by rain, demonstrating the most profound worsening of water quality from rain-related contamination of any tributary studied by Riverkeeper to date. This points to the need to reduce stormwater runoff in cities and villages, and on farms.
